What are your go to events for shocking people into learning about US imperialism in South America?
The overthrow/killing of Salvador Allende is the strongest in my opinion. What else would you pick?
I would say Halls Of Montezuma, but it's so far back that it's easily handwaved.
It's kinda hard to name just one thing the fuckery has been ongoing for a while now.
I dunno, how about anything in the neighborhood of School of the Americas? That net will catch every single coup and genocide and set of death squads in South America in the last 70 years or so.
